摘要
提出了一种下一代网络的瓶颈带宽测量方法——IPv6-pckt-pr。该方法在OPNET仿真环境下,以自相似业务流为背景流量,给探测报文赋予相同的流标签,同时将其业务类别设置为最高级,通过发送不等长的探测包对测量端到端瓶颈带宽。分析与实验表明,该方法的测量结果准确度较好,分布比较集中,测量时间较短,并能有效减少测量带宽。
An end-to-end measurement method, called IPv6-pckt-pr, is proposed to estimate the bottleneck bandwidth in the next generation Internet. This method gives same flow labels to the probing packet pairs, sets the traffic class of the probing packets to the highest level, estimates the end-to-end bottleneck bandwidth by sending packet pairs of different size. The explicitly generated self-similarity cross traffic in OPNET simulation allows the research to be more efficient. Theoretical analysis and simulations show this method is accurate, with less probing time and low bandwidth expense.
